This is our test board, you can connect your PGA309 board to J* or T* of interface board.
a) USB_DAQ and Multi-Cal-Tools overview• Multimeter:
– Agilent 34401A (GPIB, Real RS232)
– TH1961 (USB-to-RS232)
• Our software “***.v1.6a” can support those three different interface– Download link:

b) Hardware configuration:
• Step 4:
(4-wire voltage output)
Notes:
(Same GND for the
below two power supply)
Power supply #1:
+Vdut =5V
-Vdut=GND
Power supply #2:
+-15V
GND16

b) Hardware configuration:
• Step 5:
(4-wire current output)
Notes:
(Float GND for
power supply #1)
Power supply #1:
+Vdut =24V
-Vdut≠GND
Power supply #2:
+-15V

c) Software configuration
c) Software configuration:
22
Windows 7 Attention
c) Software configuration:• Press “Select Model File” to select correct model file.
• Also, you can use “”Create Model File” to create a new model file.
23
c) Software configuration:
• Default Model Files for you:
24
c) Software configuration:• Press “Start Cal” and then press the four Yes and Continue with Calibration
25
c) Software configuration:• Press “Continue” to do the Fast Scan.
• For the below picture, channel 0 and 1 is ok because I only connected two sensor modules to channel 0 and 1.
26
c) Software configuration:• Press “Continue” to do the calibration
• Below result was tested with TH1961 (with USB-232 rather than GPIB).
27
c) Software configuration:• The other thing you need to pay more attention is “Address of TH1961”,
• The current address of TH1961 we used is “COM 6”.
• You need to change it in DMM script file.
• Detailed step is in the below slides:
28
c) Software configuration:• How to create a new model file to match the address of TH1961.
29
c) Software configuration:• Take voltage output as an example:
• Select “4wire_4p096_diode_USB.txt”
30
c) Software configuration:• Take voltage output as an example:
• Press “Edit DMM Script” and select “Voltage_TH1961_USB.txt”
31
c) Software configuration:• Take voltage output as an example:
• Change the COM port in the open script file. Make sure it is the same as your Multimeter(TH1961) address.
32
c) Software configuration:• Take voltage output as an example:
• After you change the script file, please save the file and re-select the script file again. Then press “save” to save the Model File.
33
c) Software configuration:• Take voltage output as an example:
• Save the Model File:
34
• Select the new Model File, then you can press “Start Cal” to do the calibration.
35
c) Software configuration:
4-wire voltage output result:
• After the calibration:
36
For current output:
• Model File:– Iout_4p096_diode_USB.txt
• DMM script file:– Current_TH1961_USB.txt
Also need to pay more attention on the address of DDM!

If you use Agilent 34401A with GPIB:
• Voltage output:– Model File:
• 4wire_4p096_diode.txt
– DMM script file:• Volt_34401_GPIB.txt
• Current output:– Model File:
• Iout_4p096_diode.txt
– DMM script file:• Current_34401_GPIB.txt
Also need to pay more attention on the address of DDM!

If you use Agilent 34401A with RS232:
• Voltage output:– Model File:
• 4wire_4p096_diode.txt
– DMM script file:• Voltage_34401_rs232.txt
• Current output:– Model File:
• Iout_4p096_diode.txt
– DMM script file:• Current_34401_rs232.txt
Also need to pay more attention on the address of DDM!
